J=x
d=3+x
o=2d, o=2(3+x)=6+2x
j+d+o=x+3+x+6+2x=4x+9
1) 63-13=s
2) 73-7=?
4) 80-17=?
6) ?-18=74
That's all I know :)
Answer:
you are correct with -0.0081
Step-by-step explanation:

<span>By the time firework a has been launched, firework b has already been launched for 0.25 seconds, so if we treat the two as equations, then
a = 220 (t)
b =</span> 220 (t) + 220 (.25)
<span>And we want to know when these two equal eachother, as that's they will both detonate.
220t = 200 t + 200 (.25)
20t = 50
t = 2.5</span>
